'LTO all/whom it may concern:

Be it known tha1; ]2 RALPH MU'RPH'Ya citizen of the United States, Vanda resident.

.of Syracuse, in 4th'e'county of Onondaga and State of New York, haveinvented a certain new and useful Dust-Proof Cap, of which thefollowingis av specification.

Thisl invention hasrfor its .object a partieularly simple and eiicientdust-proof cap for the'antifric'tioii bearings of wheelsysuch as.'vehicle wheels, -which is .particularly simple in construction, andhighly eiiicient in vusen` and it consists in the'novel combinations.and featuresof construction hereinafterset forth and claimed.

6. The combination with an axle, a wheel having a hub mounted on theaxle, and antifriction bearings located in the hub; of a I dust-proofcap comprising a ring mounted on the axle at the inner side of the huband being angular in cross-section with the angle thereof facing thehub, and having inner and outer lconcentric pads, the inner pad beingarranged in' the angle of said member, and a ring in the form of achannel in crosssection fixed to the hub with its channel facinglaterally and inclosing the outer pad with the inner side wall of thechannel extending between the pads, substantially as and for the purposeset forth.

7. A dust-proof cap for bearings comprising annular members, each beingangular in cross-section and including flat flanges and cylindricalflanges which meet to form the angle, said members being arranged withthe cylindrical flanges extending toward each other, concentric padscarried by one of the members on the side thereof' opposed to the other,and the cylindrical flange of the latter extending between the pads,substantially as and for the purpose described.
